Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of extending a life of a bearing of a polygon motor insusceptible of variation or deterioration with the passage of time of the polygon motor. SOLUTION: This light scanning type image forming apparatus 1 comprises a printer engine 40 having a polygon motor of which the rotation speed can be controlled to be in an arbitrary one, a rotating deflector driven thereby and a motor control means 41 for controlling the rotational speed and a controller 31 that controls the whole apparatus including the printer engine 40. The image forming apparatus 1 is connected to a host computer 70. The polygon motor is stopped in the stand-by condition. When the image forming apparatus 1 is set so as to perform the printing only by a single pixel density, after the controller 31 receives a printing instruction from the host computer 70 the controller 31 immediately sends a request for rotation of a polygon mirror to the printer engine 40.  After completion of image processing in the controller 31, the controller 31 sends a request for printing to the printer engine 40.

Filed: 1995-01-23
Abstract: PURPOSE: To obtain high noise immunity in a steady-state by providing a 1st drive circuit providing a gate voltage to a gate electrode of a switching element via a resistor and a 2nd drive circuit providing a gate voltage to the gate electrode via a delay means to the switching element so as to suppress a surge voltage in a transient state. CONSTITUTION: When a gate voltage 5 transits to an On state, an auxiliary switching element 3a is conductive, the voltage of a positive gate voltage source 6p is impressed to the gate electrode of a switching element 1 via a resistor 2a. On the other hand, when the voltage 5 is switched from on OFF state to the On state, an auxiliary switching element 3c is conductive with the delay of a time constant specific to a 1st delay means 7a and the voltage from the positive gate voltage source 6p is impressed to the gate electrode of the element 1 via a resistor 2b. Thus, a surge voltage is suppressed in the transient state when the element 1 is nonconductive and a high noise immunity is obtained even in a steady state of ON and OFF states.

The pins 4 are fixed onto the base 5 to fasten the base 5 to the plate 6. The net 8 is held by the base 9 slightly below the tips of the pins 4. When the mterial 1 is now placed on the pins 4 and is subjected to cutting, the mterial 1 is supported by the pins 4 during cutting. The roughness of the cut surface of the material 1, working speed, pickup of dross, etc. are thus not changed as compared with the conventional type and the material can be held by the pins 4 and the net 8 upon completion of cutting. The rate of rising is suppressed extremely low even if the member inclines and therefore the collision between the head part of the working machine and the member 7 is averted and the damage to the respective parts is prevented.

Abstract: PURPOSE:To part a stamper formed by the master disk without catching and to enable the production of a substrate with good reproducibility by inclining the edge parts of guide grooves at a specific angle or below with the surface of the substrate. CONSTITUTION:A photoresist is applied on the substrate 1, is exposed via patterns of guide grooves, etc., and is developed to form the patterns 2 having the edge part 3 rising nearly perpendicularly to the surface of the substrate 1. The patterns 2 are then post baked at the temp. at which the patterns 2 soften so that the patterns are changed to the shape of (b) by surface tension. Dry etching is then executed to incline the edge parts 3 of the patterns 2 to <=30 deg. angle with the substrate 1. Finally, the remaining photoresist is removed to obtain the etching master disk (d) having <=30 deg. edge angle theta. The stamper is parted without catching and the shape of the guide grooves are maintained if the patterns are transfered by using the stamper formed by such master disk.

Abstract: PURPOSE:To decrease the burden of a CPU and improve the rate of response to input-output devices by enabling executing to be started only when predetermined conditions are satisfied only by the response from a lower device as an input-output instruction. CONSTITUTION:A collating circuit 14 selects one out of the registers 12, 13 or 8 displayed by the data D2 transmitted from a condition decoder 10 and applies the output thereof to an instruction CCW execution circuit 5 that the channel perse is ought to execute. When the contents of the I/O state register 8 are decidied to be BUSY in the circuit 14 and the nonestablishment of conditions are announced to the circuit 5, the circuit 5 informs of that effect to a CPU. Thereafter, the circuit 5 successively monitors the operation state of the input-output devices through the control signal line, not shown. Here, if the contents of the lower device register 8 are informed to the circuit 5 as the condition establishment in the circuit 14, the circuit 5 reads out the information from a main memory MEM and starts processing based on the instruction. Thereby, the burden of the CPU is reduced and the response speed to the device 8 is increased.
